Description.

See Arzanlou et al. (2007) and Hernández-Restrepo et al. (2020).

Notes.

Thysanorea is characterised by micro- to macronematous, dematiaceous conidiophores that are simple or apically branched, bearing terminal or intercalary, holoblastic, polyblastic conidiogenous cells. Conidia are solitary, acropleurogenous, transversely septate, pale brown, and variable in shape, most commonly oblong, obovoid, or fusiform. In contrast, the associated synasexual morph is phialidic.

Three species previously classified in Uncispora were shown to be congeneric with Thysanorea and are here formally transferred to the genus, with new combinations proposed below.
